If you’re going to shave Emma Stone’s head on camera, it's best to get it right the first time.

The two-time Oscar best-actress winner brings baldness back in a big way with director Yorgos Lanthimos’ dark comedy “Bugonia” (in select theaters Oct. 24, nationwide Oct. 31). Following their previous collaborations “The Favourite,” “Poor Things” and “Kinds of Kindness,” Stone stars in the new film as Michelle Fuller, a high-powered CEO of a biomedical corporation who a couple of conspiracy-theory cousins believe is an alien bent on world domination.

Early in the film, Teddy (Jesse Plemons) and Don (Aidan Delbis) forcefully kidnap Michelle, and Teddy has Don shave her head so she can’t communicate with her mothership.

In the scene, Michelle is unconscious. In real life, Stone was “just sort of meditating there, telling myself to stay still because if I opened my eyes or flinched, it would really mess things up,” says the actress.
